X Title: Expand template argument type deduction by pfultz2 · Pull Request #8688 · cppcheck-opensource/cppcheck

Description: Previously we only did type deduction when the argument that was passed was a literal(ie f(0)). This expands this to handle variables and expressions. There is no varid/SymbolDatabase/ValueType information at the TemplateSimplifier stage so it uses a token-based parsing to try and deduce the type. If it can deduce the type then it will skip instantiating the function. There is still a lot of gaps here that could be addressed in the future. Ideally, I would like to see if the logic from SymbolDatabase/ValueType could be reused here using a shared utility.
